SPECIFICATION forming part of Letters Patent No. 488,492, dated December 20, 1892..

Application filed August 31, 1892- Serial No, 404,639. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES ZIMMERMAN, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Shutter-\Vorkers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a horizontal section of the device with shutters closed. Fig. 2 is a similar section with shutters opened.

a Fig. 3 is a horizontal section with shutters partially opened. Fig. at is a detail view of casting or lug. Fig. 5 is a section of same taken on line y 3/ Fig. i. Fig. 6 is a detail view of guide. Fig. 7 is a section of same on line a; m Fig. 6. Figs. 8 9 l0 and 11 are detail views.

This invention has relation to certain new and useful improvements in shutter workers; and it consists in the novel construction and combination of parts, all as hereinafter described and pointed out in the claims.

Referring to the accompanying drawings, the letter A designates the window sill, B the sash, and O, C, the blinds or shutters.

D, D, designates the shutter-working devices, which constitute my invention. As the devices for working the two shutters are each an exact duplicate of the other, it will be suf: ficient to confine the detailed description to but one.

Secured to the inner face of the shutter near the hinged edge thereof is 2. lug or casting E (shown in detail in Figs. 4 and 5) which is of somewhat peculiar construction, consisting of a fiat, extended, plate-like portion, having near one end an integral horizontal projection E, cast with an interior chamber e, which is narrowed or contracted at the outer portion. In the plate portion are formed perforations, by means of which the device is attached to the shutter, and through the outer contracted portion of the projection is an intersecting vertical aperture 0t.

F designates the operating rod, which is formed in two sections F, F, connected by a' pivot pinf. The outerend of the outer section nection of the parts should it be desired to remove the shutter. Said rod works on the surface of the sill, and is provided with a guide G. Said guide consists (as shown in Figs. 6 and 7) of a casting secured to the sill, and formed with a horizontal slot 9 through which the said rod' passes. Seated in said slot and acted upon by a spring his a bearing block H, having oblique bearing faces 71.. By this arrangement,a guide bearing is provided for the rod at whatever angle it may assume with dilferent positions of the shutter. casting has an extension, formed with a lip or catch 1', over which the outer section of the rod passes (as shown in Fig. 7) when the shutter is closed. The position of the sections at this time is such that said lip forms a lock which prevents the shutter from being opened until said section is raised sufficiently to disengage said lip. This arrangement is provided in case it is desired to lock the blind from the outside when access cannot be had to the fastening hereinafter to be described.

In order to lock the shutter when open to its fullest extent, as shown in Fig. 2, an angle iron or plate K is provided, such as shown in detail in Fig. 11. This iron or plate is secured to the sill in oblique position outside of the sash, and its vertical portion is bent so as to At I, said form a slightly acute angle with the base or horizontal portion. By reference to Fig. 2 it will be seen that when the shutter is wide open, the inner section of the rod assumes such an angle with the outer section as to take a bearing against said angle iron and prevent the shutter from swinging to. To close the shutter from the inside, however, it is only necessary to pull inwardly on the inner section, which is provided with a finger piece 70 for the purpose. To close the shutter from the outside, it is first necessary to push the inner section back sufficiently to clear the iron or plate K, when the shutter may be closed With the hand, and locked in the manner hereinbefore described.

To permit the play of the rod F, and to form a further guide therefor, the lower horizontal face of the sash is cutaway at Z, said cut-away portion being extended, along the edge of the sash at Z, Z. Secured to the edge of the sash is a plate L, which is notched to correspond with the cut-away portion Z, and in the guides or recesses formed by the said plate and by the cut-away portions Z, Z, is a sliding plate M, having therein a notch m, sufficiently Wide to receive the said rod. As the rod assumes its various angular positions, this plate slides to and fro, and compensates for the movement of the rod.

To form a positive lock for the shutter when closed, and also when partially open at different angles, I provide the fastening devices now to be described.

Referring to Figs. 1 2 and 3, the inner end portion of the inner rod section is formed with a series of holes 71, any one of which is designed to engage with a pin it secured to the sill. Said pin may be on the sill, to engage the rod when in the positions shown in Figs. 1 and 3, or on the casing, as shown in Fig. 10, or elsewhere, it being immaterial What is the angular locked position of the inner section with relation to the outer section.

Having described this invention, what I claim as new and desire to secure by Letters Patent is:

1. The combination with the jointed rod, of the guide therefor, said guide being afiixed to the window sill and comprising a plate or casting having a slot therein for said rod, a bearing'block, having oblique bearing faces, seated within said slot, and a spring acting upon said block, substantially as specified.

2. The combination with the jointed rod, of the guide therefor, said guide being affixed to the window sill and comprising a plate or casting, having a slot therein for said rod, a bearing block in said slot, a spring acting upon said block, and an extension on said plate or casting, having a lip or catch forming a lock for said rod, substantally as specified.

3. The combinationwith thejointed rod, the guide therefor having the movable, springactuated bearing block, and the lock or catch, of the sash having the cut-away portions Z, Z, Z, the notched plate secured thereto, and the notched sliding plate, substantially as specified.

4. The combination with the shutter having the integral chambered lug or projection, the jointed rod secured loosely at one end within said lug or projection, and the adjustable securing devices for the other end of said rod, of the guide affixed to the sill and slotted for said rod, its catch or look the movable sliding guide in the sash, and an angular plate affixed to the sill outside of the sash, and forming a lock for said jointed rod when the shutter is.

opened, substantially as specified.

In testimony whereof I affiX my signature in presence of two witnesses.
